Upper Gorge is a gravity dam located in Bishop, California, along the Owens River. Completed in 1953, this structure stands at a height of 44 feet and has a hydraulic height of 35 feet. With a storage capacity of 26 acre-feet and serving the primary purpose of flood risk reduction, Upper Gorge plays a crucial role in managing water resources in the region. The dam is under the jurisdiction of the California Department of Water Resources and is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality.

Despite its age, Upper Gorge has been assessed to be in satisfactory condition with a low hazard potential. The last inspection was conducted in September 2019, with a regular inspection frequency of once a year. In case of emergencies, such as potential inundation events, the dam's emergency action plan (EAP) status and preparedness remain unclear, indicating a potential area for improvement. Overall, Upper Gorge serves as a vital infrastructure for flood risk reduction and hydroelectric purposes, contributing to the water management efforts in the Mono County region.

With its location in the picturesque Mono County, Upper Gorge not only provides flood protection but also adds to the scenic beauty of the area. Managed by local government authorities, this dam stands as a testament to human ingenuity in harnessing water resources while also highlighting the need for ongoing maintenance and preparedness for any potential risks. For water resource and climate enthusiasts, Upper Gorge presents a fascinating case study of dam infrastructure in California and the importance of effective regulation and inspection to ensure public safety and water security.
